So this isnt really so much an issue, but its a technical question so figured this was the best section to ask in. Problem is, i download visual novels to my pc as i use it the most, and so its more convenient. However there are quite a few times when i wish i had the same VN on my laptop. My question is, is it possible to download all the required files of a VN to an external hard-drive, so as to easily switch between using to separate machines with the exact same save data?
